I have undertaken university and industry-based research from New Zealand’s Sub-Antarctic Islands, to the Pacific Islands, to central Europe. My research involves examination of processes from the shallow Earth, to the evolution of Earth’s mantle, to the formation of the solar nebula. This research is achieved through combinations of fieldwork, microscopic analysis (e.g., scanning electron beam analysis and laser ablation inductively coupled plasma mass spectrometry), and the acquisition of stable and radiogenic isotopes (C, O, Sr, Nd, Pb, Mg and Os).

I have been a member of the Society since the early 90's as a student and I'm the current Treasurer of the GSNZ, based at NIWA Wellington. My current research is primarily focused on post-glacial marine dispersal and depositional events on continental shelves, slopes and basins. Collaborative research within active research programmes includes the application of detailed analysis of sediment cores, event chronology, and paleoseismology, all of which use high resolution seismic, multibeam bathymetry and backscatter, and sedimentary physical properties. This work embraces a range of environmental drivers for sedimentary processes including climate, tectonics, volcanism, and human-induced land-use change. In addition, my research and commercial activities are ongoing into techniques for seafloor characterization and quantifying sediment dispersal.

Richard is the current Secretary of the Geosciences Society of New Zealand. He is a Principal Scientist and Group Manager of the Ocean Geology Group at the National Institute of Water & Atmospheric Research, and is based in Wellington. He is a petrologist/geochemist by training but also dabbles in geochronology and trace metal ecotoxicity, as well as various aspects of ocean science, particularly volcanology and environmental science. He obtained his PhD from Victoria University of Wellington, and has held various professional positions in New Zealand, Australia, the US and Japan, before becoming a part of the NIWA furniture in Wellington.

I am a paleoecologist who uses biotic and abiotic proxies preserved in lake sediments to reconstruct past environments. My particular expertise is with the Chironomidae (Class: Insecta, Order: Diptera): non-biting midges who's lifecycle is highly dependent on temperature. I am particularly interested in  using paleoecology to understand both water quality over the last millenium in New Zealand and the events that characterise the last deglaciation (~20 to 10 thousand years ago) in Australasia, generally.

Lecturer in petrology at the University of Canterbury. My research focuses on the geochemistry of volcanic rocks, in particular, the role volatiles play in magmatic processes from source to eruption. I use a variety of in-situ micro-analytical techniques (e.g., electron microprobe, laser ablation inductively coupled plasma mass spectrometry, Fourier-transform infrared spectroscopy) to analyse silicate glass and minerals.
